How do I calculate comparative advantage between to producers?

Question

Say I can make either 10 sodas or 5 coffees and you can make either 12 sodas or coffees....how do I calculate who has the comparative advantage in the making of each coffee and soda?

**TWO producers

Answer 1

The cost of you producing one coffee is two sodas.
The cost of the other producer producing one coffee is one soda (if I read your question correctly).

If you specialize in soda and the other in coffee the economy will be better off.
